Make Sure the Watch is Sufficiently Charged Before Use
Check that the second hand of the watch is moving correctly in 1-second interval
movement before use. If the second hand is moving in 2-second interval move-
ment or is stopped, this indicates that the watch is not fully charged. When this
happens, expose the solar cell to light to recharge or recharge the watch by swing-
ing.
When exposing the watch to light, do not place the watch too close to the light
source. This can cause the watch to overheat which can lead to a possible mal-
function.
